Description

Technical Field

[0001] The utility model belongs to the technical field of die casting, and relates to an aluminum alloy casting die. Background Technique

[0002] A casting die refers to making the structural shape of a part in advance with other materials that are easier to form, and then placing the die in a sand mold. As a result, a cavity with the same structural dimensions as the part is formed in the sand mold. Then, a fluid with fluidity is poured into the cavity, and after the fluid cools and solidifies, a part with exactly the same shape and structure as the die can be formed. The casting die is an important part of the casting process. Aluminum alloy uses a casting die during the casting process.

[0003] An aluminum alloy casting die disclosed in Chinese Patent CN216729431U includes a base, a first support rod, a second support rod, a first guide post, a second guide post, a third guide post, a first die, a second die, a rotating shaft, and a feeding barrel. When pouring materials into the first die and the second die, the second connecting shaft drives the convex block to abut against the bottom of the first die, so that the first die and the second die can vibrate up and down, thus avoiding the generation of air bubbles in the materials in the first die and the second die.

[0004] This casting die vibrates the first die and the second die up and down by the convex block. When there is a large amount of material in the first die and the second die, the material is likely to move up and down as a whole with the first die and the second die, resulting in a poor defoaming effect.

[0046] Working principle:

[0047] During use, pour the aluminum alloy solution material into the charging bucket 6, start the motor 4, the output shaft of the motor 4 drives the connected first rotating shaft 5 to rotate, so that the charging bucket 6 rotates, and the other first rotating shaft 5 rotates.

[0049] And the first rotating shaft 5 will drive the first pulley 7 to rotate, and through the belt 8, the second pulley 9 is driven to rotate, so that the transmission shaft 10 and the first bevel gear 11 rotate.

[0050] The first bevel gear 11 drives the second bevel gear 12 to rotate, causing the second rotating shaft 13 and the first turntable 15 to rotate. This causes several tapping rods 16 to rotate. Since the tapping rod 16 is composed of an elastic rod and a tapping ball, when rotating, the tapping ball hits the first mold 24 and the second mold 25. Then the elastic rod deforms and separates from the first mold 24 and the second mold 25. The next tapping rod 16 continues to hit the first mold 24 and the second mold 25, causing the first mold 24 and the second mold 25 to vibrate, achieving the purpose of defoaming.

[0051] At the same time, the transmission shaft 10 drives the worm 17 to rotate, causing the worm gear 18 and the third rotating shaft 19 to rotate, and the second turntable 20 to rotate. This drives the first mold 24 and the second mold 25 to rotate, enabling the tapping rod 16 to tap different positions on the first mold 24 and the second mold 25, further improving the defoaming effect.

[0052] After the feeding is completed, the motor 4 rotates the injection barrel 6 to the vertical state for convenient use in the next time. And the material is formed inside the first mold 24 and the second mold 25.

[0053] Start the electric telescopic rod 22 to push the slider 23 to slide inside the chute 26, separating the second mold 25 from the first mold 24, and then the formed product can be taken out.

[0054] After that, the electric telescopic rod 22 pulls the second mold 25 to one side of the first mold 24 for mold closing and continues to be used.

[0055] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
